The present invention relates to a loon for manufacturing fabrics ofWlllOW and other rods and materials which are of longitudinally taperingform, such as nettles, raniie and so forth. Above a sliding beamdesigned to hold the lower ends of the warps, swing warp guides areprovided, capable of being brought into their end-positions alternatelyby means of rails sliding-at right angles to the vertical plane of theloom. Devices are also furnished for enabling the weft-material to beintroduced between the swungwarp's. For beating-up the weftstriking-devices, passing between the warp guides, are provided; l

A form of construction of the invention is shown in the accompanyingdrawings, in which I v Fig. l is a front elevation. r

and hold the lower ends of the warpsand thereby support. the lowerportions of the warps and the formed fabric as for ned in the Weavingoperation. :The riders are held in posit on'durlng WOifkHlgOf the 100111by means of set-screws 55 (Fig. 2), Aboveithe riders, tubes 57, havingheads 56, are suspended in forks 58, their lower ends extending to theproximity of the top of the riders 54. The guide-rollers 59 arehorizontally slidable, parallel. to each other, in guide grooves 60provided atthe frame uprights 46, 47. The heads "61 ofthe plungers 62abut against the guide-rollers 59 and are acted upon by springs 63 (Fig.2), housed partly in the plungers .62 and partly in the cylindricalcasing 64 which receives the latter. The tension otthe springs 63andthusthe-pressure of the guide-rollers 59, at first against the riders 54and, subsequently against the fabric, can be regulated by levers 65fulcrume d at '66 to the uprights 46, 47. The levers 65 are coupled tohand-levers 67' (Figs.2,17, 18), fulcrumed at 68 .to the up rights 46,47 To maintainthe levers 67 in a given position, Qeachfis provided witha spring arm 7 O, having a tooth 69, adapted to engage between the teethof a rack 7l secured For swinging the warp guides, that isto say, thetubesl57, there are provided supporting-rails 72, 73, 7,4,75,'horizontally slidable in guides7 6 on the uprights ,46, These railsare furnished with pusher-bars,extending in the direction of motion,whose ends are recessed to receive the tubes 57., The rail 72 isprovided with the p ushers ,7 7, the rail73with the pushers 7.8,the rail74 with the pushers 79 and the rail -75 with the push ers 8 0, The upperfaces'of'the pushers all lie in the saine 'horiz'oiital plane. Theendsof the rails.727 5 are provided with outardly extending hooked arinstowhich. are attached springs.81,.whose other-end is s cured tothebr'ackets 82 eXtendi-ngfrorn the draw the rails 72-75 outwards'. Theends inc of the branches of the cord-system 85-86, se-

. cured to the levers 83, 84, are attached to the said hooked arms ofthe rails 72-7 5, whereby these rails can be pulled against the actionof the springs 81. The branch cords pass over pulleys 87 to the hookedarms of the rails 72-75 in such manner that by descent of the end of thelever 83 attached to the cord 85, the lower rails 73, can at the sametime be drawn towards the center of the loom, while by the like movementof the lever 84: the two other rails 72, 74 can be similarly drawn upon,in each case against the action of the springs 81. The actuation of thelevers 83, 84, which are fulcrumed on the shaft 89, mounted in bearings88, is effected by means of cam-disks 90, 91 (Figs. 10, 11), whose camslie diametrically opposite to each other on the shaft 92, which turns inthe bearings 88 and carries the driving-pulley 93.

The weft beating-up levers 95 with the shaft 97, which is mounted on thebearings 96'on the uprights 46, 47, are arranged to rock, so that theirheads 98 can pass between thetubes 57 to the center of the loom. Forthis purpose, on the shaft 97 is mounted a double-armed lever, to whoseone arm 99 is attached the upper end of the spring 100, the

lower end of which is fastened to the hook 101, projecting from theupright 47 2).

The otherlever-arm 102 (Figs. 3,15, 16) is the cam-disk 107, having twodiametrically opposed cams108, mounted on the shaft 92.

The weft-material is shot-in by means of a shuttle 110 (Figs. 8, 9),having on itsback a clamp 111 to grip the weft. The to and fro motion ofthe shuttle is imparted by pickermechanisms, provided upon the uprights46, 47." These mechanisms have each a casing 115, in which is provided apicker 117 (Figs.

6, 7), furnished with a liningpiece 116 to receive the tip ofthe shuttle110. The picker 117 has a pin 118, guided by the slots 119' of thecasing 115, which is closed by a cover 120., The spring 121 presses withone end against the picker 117 and with the other end against the stop122. and its tension can be regulated by means of the set-screw 123.Below the casing 115 is a cam-disk 124, whose cam 125 projects into thepath of the lower end of the pin 118. The cam-disk 12 1- is mounted faston the shaft 126, which receives motion by means of the bevel gearing114 from the shaft 127, which itself is driven by the shaft 92 with theaid of chain-gearing 128. 130 are bridges on which the shuttle 110 liesbetween the casings 115 .and pusherbars 77-80 of the rails 72-75; and131 is an ejector pivotally secured to the part 132, by means of whichthe weft-material after being shot through the shed is expelled from theclamp 111. One of these ejectorsis provided at each standard, in suchmanner that only that weft is ejected which is shot from the oppositestandard. I

The forks 58 are adjustably secured to the rails 135 (Figs. 13, 14:),which, are supported by the brackets 136 projecting from the frameuprights, and they are held in position by screw-boltsand nuts133,.slidable 1n grooves 134, in which manner the distances between theindividual tubes 57 can be altered as desired. The forks 95 forbeating-up the weft and the riders 5i and pusher-bars 77-80 of therails7 2-7 5, are likewise adjustable as regards distance apart.

Weaving may be carried on as follows i- The beam 45 is first elevated tosuch height that the riders 5st enter between the guiderollers 59.Hereupon the warps are inserted from above, through the tubes 57 intothe bores 53 of the riders or warp end retainers.

The loom can now be started. The cord is first operated and the rails72,75 and their pusher-bars 78, 80 will thus be advanced towards therails 7 2, 74C and their pusher-bars 77, 79, and the tubes 57 willbeswung out into their end-positions, every alternate warp being bentforwardly and theintermediate ones backwardly. During the sliding of therails 73-75 a shuttle 110, filled with weft, is laid by hand upon theright-hand bridge 130 against the picker 117, brought into itsendposition by the operation of-the cam 125. Following upon the motionof the pusher-bars 78-80, the cam 125 releasesthe pin 118 and theshuttle 110 will be impelled by means of the spring 121 to the otherside of the loom, traveling between the tubes 57 on the pusherbars ofthe rails 72-75. As soon as the weftmaterial has been shot through theshed, it is expelled from the clamp 111 by the ejector 131 and the weftthat has been shot-in is battered or forced down by the heads 98 of thebeating-up levers 95 actuated by one of the cams 108. Hereupon theshuttle is provided withnew weft-material..and owing to furactuated bytheca'm91. will draw the cords 86 and movethe rails 72, 74, wherebytheir pusher-bars 77, 79 will swing the tubes 57 into their otherend-position. The other picker mechanism willnow throw back the shuttle110, with new weft-material, to the opposite side of the, loom. insimilar manner to that described. and the weft which has been shot-inwill then be expelled from the clamp 111 by the ejector at the otherstandard. After the weft-material has been thus shot-in the weft-beatinglevers-will force this material against the preceding. and at the sametime depress the beam 1-5 throught-he thickness of the weft-material,whilst the. warps will be drawn simultaneously through the tubes 57.When the riders 54 have been depressed beyond the grip of the rollers59, these will press against the fabric.
